Dc devices Quiz Practice Quiz | Dc devices

Q: Which of the following is a common DC voltage source?

Battery — Batteries are the most common source of DC voltage.

Q: What does 'DC' stand for in 'DC device'?

Direct Current — DC stands for Direct Current, referring to the flow of electrical charge in one direction.

Q: Which component stores electrical energy in a DC circuit?

Capacitor — Capacitors store energy in an electric field, making them suitable for DC circuits.

Q: What is the primary function of a resistor in a DC circuit?

To oppose the flow of current — Resistors resist current flow, limiting current in the circuit.

Q: Which of the following is a DC semiconductor device?

Diode — A diode is a semiconductor device that allows current to flow in one direction.

Q: What is the unit of measurement for DC voltage?

Volt (V) — Voltage is measured in Volts (V).

Q: What is the function of a diode in a DC circuit?

To allow current to flow in one direction — Diodes conduct current in only one direction.

Q: Which device converts AC voltage to DC voltage?

Rectifier — A rectifier converts AC to DC using diodes.

Q: What does a multimeter measure in a DC circuit?

DC voltage, current, and resistance — A multimeter measures various DC parameters.

Q: What is the relationship between voltage, current, and resistance in a DC circuit (Ohm's Law)?

V = I * R — Ohm's Law states that Voltage (V) equals Current (I) multiplied by Resistance (R).
